[0002] Automotive leaf springs are the most traditional elastic components in the automotive suspension system, and have the advantages of good reliability, simple structure, short manufacturing process flow, low cost, and greatly simplified structure. Automotive leaf springs are composed of multiple steel plates with unequal lengths and equal curvatures stacked together. After installation, both ends bend upward naturally. When the impact force from the road surface is transmitted to the wheels, the steel plates deform, playing a role in buffering and vibration reduction, and also having a role in guiding and transmitting force when arranged longitudinally. Most non-independent suspensions use steel plate springs as elastic components, which can eliminate the guiding device and shock absorber, and have a simple structure.
